Oscillatoria brevis (Kutz.) Gom. and some other especially odouriferous benthic cyanophytes in Norwegian inland waters

The cyanophyte Oscillatoria brevis (Kütz.) Gom. has been investigated in field and laboratory. Axenic cultures of the clone NIVA CYA 7 produced strong muddy - smelling compounds, geosmin and 2-methylisoborneol. The correlation between profuse development of benthic cyanophytes and off-flavour proble...

Zusammenfassung:The cyanophyte Oscillatoria brevis (Kütz.) Gom. has been investigated in field and laboratory. Axenic cultures of the clone NIVA CYA 7 produced strong muddy - smelling compounds, geosmin and 2-methylisoborneol. The correlation between profuse development of benthic cyanophytes and off-flavour problems indicates that these organisms are liable for the effect. The present study showed that Oscillatoria brevis was able to synthesize the off-flavour compounds concerned.
